I have a Buffalo Linkstation which runs "TwonkyServer Premium 7.1.1-dsd". Mostly it works fine, but there is a problem serving m3u playlists containing radio URLs: the XML generated by Twonky does not contain the <res> tag, and hence the player cannot play them.

In the "downloads" section of this forum, there are links to updated Twonky versions for multiple Buffalo platforms. These appear to be user-submitted solutions not supported by Lynx. I'm planning to review, to see if there's a way to update my linkstation 421 and 221. There's a known security bug in Twonky 7.7.1, but Buffalo does not seem to do anything about it.
